From sandbox to "sandbox"

During that time, the neighborhood was a combination of dirt, sand, and asphalt. Big trees were still common, and kids could run around freely. Nowadays, asphalt roads have replaced the dirt roads, skyscrapers and housing complexes were erected in the large empty ground, and big trees have been cut down. The kids now sit safely inside their parents' cars, and once they go out, the parks offer an uninterrupted experience of artificial grass.
